Sleep Number unveiled its revamped smart bed line at CES this week, starting with its new 360 bed. The bed does a lot: it automatically adjusts to your sleep position to make you comfortable; it detects snoring and elevates your head to stop your snoring; it figures out how well you slept based off your heart rate, breathing, and your tossing and turning; and it’s also got foot warmers. The foot warmers, in my professional sleeper opinion, are the bed’s true star.
